"What sort of new Macedonian nation can this be when we and our fathers and grandfathers and great-grandfathers have always been called Bulgarians? ... Macedonian as a nationality has never existed, they will say, and it does not exist now. There have always been two south Slav nationalities in Macedonia: Bulgarian and Serbian. So, any kind of Macedonian Slav revival is simply the empty concern of a number of fanatics who have no concept of South Slav history."
